ROAD DRAG.

Application filed April '5, 1924. Serial No. 704,347

To all whom it may concern:

Be it known that I, JOHN SNYDER, a citizen of the United States, residing at Jacksonville, in the county of Morgan and State of Illinois, have invented new and useful Improvements in Road Drags, of which the following is a specification.

This invention relates to road machinery and more particularly to road drags.

The primary object of this invention resides in the provision of a road dragsusceptible of various adjustments.

Another object of this invention resides in the provision of a road drag having blades assembled in such association with their corelated elements that they can readily be adjusted to perform different kinds of work.

A still further object of this invention resides in the provision of afroad drag having its blades disposed so as to permit the angular disposition thereof to be varied on either side of their plane alignment.

Aside from the foregoing objects, this invention resides in the provision of a road drag of such construction that its blades can be set independently of one another at different inclinations and their relative inclinations maintained during their adjustment on either side of their plane of alignment.

In addition to the aforesaid objects, this invention resides in the provision of a road drag constructed of an assemblage of cooperative elements directly under the control of an operator.

With these and other objects in view, this invention resides in certain novel features of construction, arrangement and combination of elements to be hereinafter set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claims and, While the present disclosure fully depicts my present conception of the invention, the right is reserved to resort to such changes in construction as fall within the scope of the claims.

In the accompanying drawings forming a part of this application: 7

, blade.

Fig. 2 is a side view thereof. Fig. 3 is a detail sectional view on line 33 of Fig. 1, showing the blades in horizontal alignment by full lines and adjusted on, different incline planes by dotted lines.

Fig. 4 is a detail perspective view of one of the adjustable axles.

Fig. 5 is a detail longitudinal sectional view and an enlarged scale of the blade adjusting block and manipulating lever therefor.

Fig. 6 is a detail perspective view of the draft tongue.

Fig. 7 is a detail enlarged sectional view on line 77 of Fig. 1.

Fig. 8 is a detail sectional View on line 88 of Fig. 5.

Fig. 9 is a detail perspective view of the upper inner end of one form of scraper Fig. 10 is a similar view of another form of scraper blade.

In the present embodiment of this invention, thenumeral 5 designates a bolst r on which is journaled axles 6 having their cuter ends bent to form crank portions 7 carrying spindles 8 on which wheels 81 are journaled. The inner ends of the axles are provided with levers 9 to permit the rotation of the axles in their bearings through the manipulation of elements to be hereinafter set forth and thus cause the crank portions thereof to elevate and lower the bolster which in turn elevates the scraper blades so the drag can be transported from place to place wi h the scraper blades out of engagement with the ground.

Extending from the bolster is a longitudinally slotted tongue 10 having a elevis 11 at its outer end and reenforced at its juncture with the bolster by a brace block 12 which supports a substantially inverted U-shaped stop-bracket 13 in close proximity to the levers 9 of the axle.

Slidably disposed in the slot of the tongue is a block 14: to which are pivotally connected the inner ends of scraper blades 15.

The scraper blades 15 extend on opposite sides of the tongue and have their outer ends supported by adjustable truss rods 16 connected to ears 17 on the slidable block. Each of the scraper blades is provided with a series of apertures 18 and, through the probolster and similar apertures 18 in the medial portions-of the scraper blades, the angularity of the scraper blades to the tongue can be established, as well as provide selecitive fulcrum points on which the scraper and elements connected therewith can be slid backwardly and forwardly on the tongue to adjust the inner ends of the scraper blades and to retain the inner ends of the scraper blades in the desired adjusted position, the notchesof the lever are seated over the stirrup. In order. to facilitate moving the lever 22 past overhanging or interfering portions of certain tractors, the same is provided with a foldable handle 24.

With the opposite sides of the bolster independently adjustable as aforesaid, through the instrumentality of the cranked portions of the axles and levers carried thereby, the scraper blades can be tilted to obtain various road mounds and, since it is important that a variable adjustment as to the tilting of the scraper blades must be directly under the operators control, the levers on the axles are connected to hand-levers 25 by links 26. The levers 25 are held in adjusted positions by pawls 27 which engage segments 28 and, to limit the forward rocking movement of the levers, carried by the axles, the movement of the links 26 is checkedby the inverted U-shaped stop-bracket 13 secured in close proximity to the levers.

l/Vith this invention fully set forth, it is manifest that a road drag of simple construction is provided and, through the provision of its adj ustability, road construction will not only be greatly facilitated but the establishment of economy will ensue as the necessity for various types of drags will be obviated.

Having thus described this invention, what I claim and desire to protect by Letters Patent is:

1. A road drag of the character set forth having a draft tongue, the combination of oppositely extending scraper blades, a slidable block connected to the inner ends of the scraper blades, a stirrup secured to the tongue of the road drag, a gravity actuated lever pivoted at its inner end to the slidable block and extended over the stirrup, and rack teeth formed on the lever and engaging the base of the stirrup.

2. The combination with a road drag having the opposed ends of its scraper blades slidably connected together and disposed on a longitudinal line passing through the road drag, a gravity actuated lever connected to the connecting means of the blades, and a stirrup in the path of the lever for supporting the same when in locked position.

In testimony whereof I affix my signa ture.

JOHN SNYDER.
